| Abstract: | A kind of air flow velocity and direction sensor which can be used in internal combustion engine is designed.Working principle of the sensor is introduced.The seneor output signal is linearized and compensated by the single chip processor.The experiment results show that the temperature stability is high,and temperature zero shift is 4.0×10~(-3) %FS/ ℃ in the range of-20～100 ℃.The accuracy of the sensor can reach ±1.0%FS.Thus its technology index can meet the design demand. |
| Keywords: | sensor air flow velocity and direction temperature compensation Lagrangian interpolation |
